Identifying deformed exoplanets with JWST and Ariel: A target selection metric for phase curve observations
Vanesa Ramirez, Yamila Miguel, Billy Edwards +2
The shape of an exoplanet encodes fundamental information about its internal structure. For close-in giant planets, strong stellar tidal forces induce measurable deformations that…
The First Hubble Detection of a Secondary Eclipse from a Rocky Exoplanet: the 5.4-hour planet TOI-2431 b
Sebastian Zieba, Billy Edwards, Samuel N. Quinn +18
We present an HST/WFC3 G141 phase-curve observation of the ultra-short-period rocky planet TOI-2431 b and detect its secondary eclipse in the near infrared. Combined with the TESS…
Super-Earth Interiors Shrink by About 10% as They Crystallise
Tim Lichtenberg, Mara Attia, Harrison Nicholls +26
Super-Earth exoplanets are among the most abundant planets known, yet their bulk densities leave the interior state degenerate. The static structure models used to interpret them,…
Thermal Evolution of Lava Planets Across System Ages: Predictions for Hell of a Survey
Mariana Sastre, Tim Lichtenberg, Lisa Dang +22
Ultra-short-period (USP) rocky exoplanets can have dayside temperatures high enough to maintain permanent magma oceans, sitting at the intersection of interior geophysics and atmos…
Alkali lines at extreme densities and their impact on giant planet interior structure
Louis Siebenaler, Nicole F. Allard, Esther van Dijk +1
Alkali lines, in particular the sodium Na (5891, 5897) and potassium K (7667, 7701) resonance doublets, are dominant opacity sources in giant planets over a wid…
Coupled atmospHere Interior modeL Intercomparison (CHILI). I. Evolutionary Modelling -- Primordial Magma Oceans of Earth and Venus
Harrison Nicholls, Joshua Krissansen-Totton, Tim Lichtenberg +22
Earth and Venus represent two evolutionary outcomes arising from initially molten 'magma ocean' periods, followed by lifetimes of chemical and geophysical divergence. Their physics…
Strong and variable stratospheric CO emission from lava-planet 55 Cnc e observed with NIRCam/JWST
Ignas Snellen, Yamila Miguel, Leoni Janssen +4
Some rocky planets orbit so close to their host stars that stellar heating melts their surfaces. They offer a rare glimpse of planets in a magma-ocean state, providing an observabl…
Sensitivity of Dry Lava Planet Atmospheric Emission Spectra to Changes in Lava Compositions
Christiaan P. A. van Buchem, Rojita Buddhacharya, Mantas Zilinskas +3
The atmospheres of hot rocky exoplanets are among the first primary targets of the JWST. Interpreting their atmospheric spectra requires understanding the link between silicate lav…
Reassessing planetary composition: Evidence of rock-dominated envelopes in Uranus and Neptune
Vanesa Ramirez, Yamila Miguel, Saburo Howard
Although Uranus and Neptune are commonly classified as ice giants, their exact compositions remain poorly constrained. Recent studies of outer Solar System bodies challenge the tra…
Mean opacity tables for probing the interior and atmosphere of giant planets
Louis Siebenaler, Yamila Miguel
We present new Rosseland and Planck mean opacity tables relevant to the shallow interiors and atmospheres of giant planets. The tables span metallicities from 0.31 to 50 times sola…
Retrieving interior properties of hot Jupiters with Love numbers and atmospheric measurements
Esther van Dijk, Yamila Miguel
Understanding exoplanet interiors is crucial for interpreting atmospheric observations and constraining their evolution and formation. However, due to limited observational constra…
